Washington University in St. Louis engineers have developed a high-powered fuel cell that operates at double the voltage of today’s commercial fuel cells. It could power underwater vehicles, drones and eventually electric aircraft at a significantly lower cost. The transportation industry is one of the largest consumers of energy in the U.S. economy with increasing […]

Purdue University researchers produce a fuel cell with a new method increasing the fuel cell electrode activity at least tenfold and using 90 percent less platinum. Electric vehicles running on fuel cells tout zero emissions and higher efficiency, but expensive platinum is holding them back from entering a larger market. The 2019 Toyota Mirai electric […]

Korea’s Daegu Gyeongbuk Institute of Science and Technology (DGIST) researchers have fabricated nano-sized catalysts that could improve the performance and production of clean energy fuel cells. The team’s study results have been published in the journal of Applied Catalysis B: Environmental. Polymer electrolyte membrane fuel cells (PEMFCs) transform the chemical energy produced during a reaction […]

DOE/Argonne National Laboratory scientists have identified a new catalyst that uses only about a quarter as much platinum as current technology by maximizing the effectiveness of the available platinum. The Argonne chemists have published their study results in the journal Science. Platinum is a precious metal more rare than silver or gold. Renowned in the […]

Ruhr-University Bochum researchers have combined two concepts that make a biofuel cell as efficient as precious metal catalysts. Fuel cells that work with the enzyme hydrogenase are, in principle, just as efficient as those that contain the expensive precious metal platinum as a catalyst. However, the enzymes need an aqueous environment, which makes it difficult […]
